Actually, no.  It's still in my local tree because I have not
been able to work on it lately.  If I get a chance I could
whip-up a semi-working version by the end of the week.

However, given that there are other optimizations in the works
maybe we should wait and fix all the more obvious bugs in the
branch rather than polluting the trunk.
